How does a car battery indicator work?
Use the sight glass on the top of a maintenance-free battery to gauge the (SoC) state of charge. Typically a light green dot indicates a fully charged battery. The electrolyte solution is close to 1.265, a solution that is heavier than water (1.0).
What is the low battery indicator?
The Low Battery Indicator is a diagnostic channel that indicates the battery level of the node. It is represented by 3 possible values: 0, 1, and 2. The “0” value indicates that the battery level is good. The “1” value indicates that the battery level is low.
What is indicated by the eye or battery indicator in a sealed battery?
Battery Indicator Eye
Check the indicator eye. A red eye indicates the battery is severely discharged or the electrolyte is low. The electrolyte level is sufficient and the battery is at least 25% charged if at least some blue is showing.

Disconnect the battery to be tested from the vehicle and other batteries. If the battery has just been charged or the vehicle driven, the surface charge needs to be removed before testing.
What should a 12 volt battery read fully charged?
Fully charged automotive batteries should measure at 12.6 volts or above. When the engine is running, this measurement should be 13.7 to 14.7 volts. If you don’t have a multimeter to tell you the voltage of your battery, you can do a test of your electrical system by starting the car and turning on the headlights.
